John Nack’s excellent post lays out all the options.

1. In the Library module, select the photo you want to have a border, then switch to the Print module.
2. In the Template Browser on the left side of the application, select a Single Image template the correlates to the size you want the photo to be, such as 4 x 6 or 8 x 10.
3. In the Image Settings panel on the right side of the application, select Stroke Border. Specify a Width of the desired size (such as 10 points) and click the color swatch to choose a color, such as white.
4. In the Print Job panel, choose Print To > JPEG File. Specify the resolution and other options (sharpening, JPEG quality, etc.).
5. Click Print to File.

There. You’ve just “exported” a JPEG of your photo with a border. Now you can post it online, upload to a print service, or do whatever you do with JPEGs that have borders.

For additional Help with Print module panels and tools, see Printing photos or, more specifically, Print borders around photos or Specify options in the Print Job panel.

A second way to do it is to create a border effect in Photoshop, and then apply it to your photo in Lightroom as an identity plate. Scott Kelby shows how in the tutorial Adding cool frame borders to your photos. The tutorial is old—for Lightroom 1 and Photoshop CS3—but the principles still apply and you can do it using Lightroom 3 and Photoshop CS5.1. For another (Lightroom 1) tutorial of this technique, see Sean McCormack’s frames video.

A final way is to use an export plug-in, such as Timothy Ames’s LR/Mogrify 2 plug-in.

• Export from Lightroom to Facebook
• Export from Lightroom to Flickr
• Export from Lightroom to SmugMug
• Export from Lightroom to Photoshop.com
• Export to Hard Drive using Publish Services

Hopefully, this structure is simpler and more straightforward. Pick your service; read the instructions; bookmark it.

Don’t worry. Lightroom will find them.

If you move photos in the OS away from the location where Lightroom thinks they are, Lightroom loses the link to them. When that happens, you’ll see a little question-mark icon in the image thumbnail in the Library module, and in the Develop module, you’ll see a big message: “The file named XXX is offline or missing.”

To relink the photos, see the Lightroom Community Help topic Locate missing photos. There’s even a link to a video tutorial of the process as well.

If you move entire folders of photos in the OS and break the link in Lightroom, the folder appears dim in the Folders panel and has a question-mark icon.

To restore broken links to folders, see the Help topic Locate missing folders. The topic Synchronize folders might be useful, too.

To prevent broken links between Lightroom and the folders and photos in your catalog, remember these tips:

• Don’t move photos or folders in the Finder (Mac OS) or Explorer (Windows). Do it from within Lightroom.
• If you store photos on an external hard drive, make sure it is attached and powered on when you start Lightroom. If the drive is disconnected, Lightroom will lose the links to the photos, even if they haven’t been moved.

• Deke McClelland targets and tweaks a specific color range
• Photoshop Help walks through all the alternative approaches

As you probably know, you can work in one of two import windows in Lightroom: One is a relatively complex window in which you select the source photos, decide how to import, and then specify an array of import/destination options in panels on the right side of the window.

Or, you can click the Show Fewer Options button to work with just a bare minimum of import options.

But did you know that there’s a third way to work? In the full import window, you can use a keyboard shortcut to display only the import panels you want to see and hide the others from view. Right-click (Windows) or press Control+Command and then click (Mac OS) any of the panel headers on the right side of the window to open a context menu. You can show or hide all panels; expand or collapse them; select only those you want to view (the ones whose settings you always need to customize); or enter Solo Mode. You can use the keyboard shortcut on the Source panel on the left side of the window, too, but I tend to need to keep that panel open.

For more information, see the following Help topics:

• Import photos into a catalog (working in the full import window)
• Import using fewer options (using the minimal import window)
• Managing panels and the screen view (working in Solo Mode)

There. Now you’ve learned something, too.

Photoshop legend Michael Salinero provides several options, including a clever technique that uses Smart Objects to create flexible package layouts.

The new Select > Refine Edge produces far better results and is way more flexible. Fine detail like wispy hair is quickly captured, often without requiring any touch up. It’s really pretty stunning. If you want to fine-tune the results, however, non-destructive processing lets you revisit things at any time, simply by tweaking the related mask. (In contrast, the old Extract command permanently erased pixel data. Bad news when you want to revert a saved file.)

Here are a few online resources to get you started with Refine Edge:
